Bosch Rexroth HMS01.1N-W0054-A-07-NNNN – High-Dynamic Single-Axis Servo Inverter | IndraDrive M Platform
Engineering Background: The IndraDrive M series represents Bosch Rexroth’s flagship modular drive architecture, engineered for demanding motion-control applications in machine tools, packaging lines, and precision automation cells. The HMS (High-performance Motor Supply) topology integrates the power supply and axis inverter into a compact, DIN-rail-compatible module, reducing panel footprint and simplifying commissioning.
Product Positioning: The HMS01.1N-W0054-A-07-NNNN is a single-axis inverter rated at 5.4 A continuous output current, designed to pair with IndraDrive M supply units (HMV/HMS) in a shared DC-bus topology. It targets OEMs and system integrators who require deterministic torque/speed response, safe-motion compliance, and seamless integration with Rexroth IndraMotion or third-party PLCs via SERCOS III / PROFIBUS / EtherCAT fieldbus options.

Engineering Advantages
- Shared DC-Bus Architecture – Energy regenerated by decelerating axes is instantly reused by accelerating axes, cutting peak demand by up to 30 %
- Integrated Safe Torque Off (STO) – Eliminates external safety contactors; meets PLd / SIL 2 without additional hardware
- Plug-and-Play Motor Recognition – Electronic nameplate (EnDat / Hiperface) auto-configures motor parameters at first power-up
- Scalable Fieldbus – Base SERCOS III; upgrade to PROFIBUS DP, EtherCAT, or PROFINET via snap-in option cards without rewiring
- Compact DIN-Rail Footprint – Modular side-by-side mounting minimizes cabinet width vs. standalone drives
- Rexroth IndraWorks Engineering – Unified commissioning, diagnostics, and oscilloscope tool across the entire IndraDrive family
System Architecture & Signal Flow
The HMS01.1N-W0054-A-07-NNNN slots into an IndraDrive M power section (HMV01 or HMS01 supply module) via the DC-bus connector bar. The supply module rectifies three-phase mains and maintains the shared DC link. Each HMS axis inverter draws from this link and synthesizes a variable-frequency, variable-voltage output to the servo motor. The SERCOS III ring (or alternative fieldbus) carries cyclic set-point data (position, velocity, torque) from the motion controller at 250 µs … 4 ms cycle times. The integrated STO channel accepts a 24 V DC safety signal; removing it disables the output stage within 10 ms without requiring a main-contactor trip.

Technical FAQ
Q: Can the HMS01.1N-W0054-A-07-NNNN operate as a standalone drive without an HMV supply module?
A: No. The HMS axis inverter requires a shared DC-bus supply unit (HMV01 or HMS01 supply section). It does not contain an internal rectifier.
Q: Which motors are compatible?
A: All Rexroth MSK, MKD, MKE, and MHD servo motors with EnDat or Hiperface feedback are natively supported. Third-party motors can be configured via the generic motor interface in IndraWorks.
Q: What fieldbus does the base unit support?
A: The -07-NNNN variant ships with SERCOS III as the base communication interface. PROFIBUS DP, EtherCAT, PROFINET, and DeviceNet are available via optional communication modules (requires -07-NNxx suffix).
Q: Is the STO function certified?
A: Yes. STO is certified to IEC 62061 SIL 2 and EN ISO 13849-1 PLd, with a PFH of < 10⁻⁸ /h.
Q: Can I upgrade firmware on-site?
A: Yes, via IndraWorks Engineering software over the SERCOS III or USB service interface. Rexroth firmware files are available from the Bosch Rexroth Download Center.
